  The First Structure–Activity Relationship Studies for Designer Receptors Exclusively Activated by Designer Drugs

  摘要：

  Over the past decade, two independent technologies have emerged and been widely adopted by the neuroscience community for remotely controlling neuronal activity: optogenetics which utilize engineered channelrhodopsin and other opsins, and chemogenetics which utilize engineered G protein-coupled receptors (Designer Receptors Exclusively Activated by Designer Drugs (DREADDs)) and other orthologous ligand receptor pairs. Using directed molecular evolution, two types of DREADDs derived from human muscarinic acetylcholine receptors have been developed: hM3Dq which activates neuronal firing, and hM4Di which inhibits neuronal firing. Importantly, these DREADDs were not activated by the native ligand acetylcholine (ACh), but selectively activated by dozapine N-oxide (CNO), a pharmacologically inert ligand. CNO has been used extensively in rodent models to activate DREADDs, and although CNO is not subject to significant metabolic transformation in mice, a small fraction of CNO is apparently metabolized to clozapine in humans and guinea pigs, lessening the translational potential of DREADDs. To effectively translate the DREADD technology, the next generation of DREADD agonists are needed and a thorough understanding of structure activity relationships (SARs) of DREADDs is required for developing such ligands. We therefore conducted the first SAR studies of hM3Dq. We explored multiple regions of the scaffold represented by CNO, identified interesting SAR trends, and discovered several compounds that are very potent hM3Dq agonists but do not activate the native human M3 receptor (hM3). We also discovered that the approved drug perlapine is a novel hM3Dq agonist with >10 000-fold selectivity for hM3Dq over hM3.

  The present disclosure relates to a method for investigating blood-brain barrier properties and brain metabolism using an insect brain as a model system. The method comprises dissecting out an insect brain comprising the compound eyes, and exposing the brain and compound eyes to a medium comprising a chemical compound. The method allows for the investigation of various properties, including blood-brain barrier permeability of compounds, the effect agents have on the blood-brian barrier, and various aspects of brain chemistry including distribution and metabolism of agents within the brain. The method finds various uses, such as an in vitro screening model as part of drug development, or as a methodology to investigate the impact of various agents on brain chemistry and the integrity of the blood-brain barrier, both in vitro and in vivo.
